Hi all,

we are using ES 1.3.7 and facing some slowness in cluster.

while analysing logs, found some same message repeated

Hey,

this is by far not enough information to help. Please take your time to describe your setup properly.

This is a debug message (are you logging on debug level by default? why so?). This message means that a HTTP was closed unexpectedly (maybe a network issue, impossible to tell).

Also, you should upgrade, Elasticsearch 1.3 is really old and you are missing a ton of bugfixes...
